There is a delay and lag when copying in Adobe Illustrator 2025 29.5.141
When using Adobe Illustrator 2025, there is a delay and lag when copying. When performing a Ctrl+C copy of graphics or text, or when manually dragging, there is a delay and lag in the response, and the copy does not appear immediately. If a zoom operation is performed during a Ctrl+C copy, the delay and lag become even more pronounced.

Previous versions all had delays, and this was true for any file

Thanks for reporting this. Did you start noticing the delay in this version (29.5.1), or was it present in earlier builds as well? Also, does this happen with specific types of files or any file in general? Any additional detail you can share will help us investigate further.
